C. K. RICE, o'E MARLBOROUGH, MASSACHUSETTS Letters Patent No. 84,216,dated November` 17, 1868.

l coAL-SIFTER.

The Schedule referred to :in these Letters Patent andmakng part oftheame.

Know all men by these presents:

That I, C. K. RICE, of Marlborough, county of Middlesex, Commonwealth ofMassachusetts, have invented certain new and useful improvements inCoal-Sifters; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, in which-Figure 1 represents a perspective view of my improved coal-sifter, thecover being raised, to show the position of the sieve.

Figure 2 represents a section on the line xix'.

Figure 3 represents a section on the line y-y, showing the position ofthe sieve and trough.

Figure 4 represents a .section on the line z-z, showing the manner ofconnecting the sieve and trough.

To enable those skilled in the art to which my inj veut-ion belongs, tomake and use the same, I will proceed to describe it more in detail.

The nature of my invention consists, first, in the peculiar combinationof the ash-box, coal-box, and separating-device, as hereafter described;second, in the peculiar combination ofthe main .sieve and seconda-rysieve, as shown; and, third, in the combination, 'with coal-box, ofcoal-sieve frame, as described hereafter.

My improved coal-sitter consists of the ash-box A, sin'mounted by theremovable coal-box B, in'which are arranged'the sieve-frame G andsecondary sieveframe D.

The sieve-frame C is connected to the side of the coal-box B by thepivot a in the piece a', on the inside of the coal-boxB, the oppositeend of the frame resting on the projection b, fastened to o1' projectingfrom the inside of the coal-box B, and upon which it can freely slideback and forth laterally.

It is furnished with a handle, d, proj ecting through theHside of thecoal-box B, as shown in the drawings, by which the proper motion-isimparted to sift the coal.

The sieve E is made inclined toward the corner, e, where there is anopening in the side j, below which is placed the end of the frame D,which rests upon the projection I), and is connected to the sieve C by astrap of metal, g, as shown in tig. 4 of the drawings.

The 'ame D inclines downward, its outer end passing out through anopening, h, in .the side ofthe box B.

The bottom of the frame D is made of wire netting H,"to admit of thepassage of dust and ashes into the ash-box A.

The partially-burned coal and cinders being placed upon the sieve-bottomE, the cover F is shut' down, and the sieve shaken bymeans `of thehandle d. The

pieces of coal which are too large to fall through the sieve E pass outof the opening in the side f, into the trough-sieve D, and are thereconveyed or guided to the outside of the box B, and drop into the hod orother receptacle placed under the end'D of the trough for that purpose,the whole operation being accomplished with but little trouble fromdust, and, besides, requiring but little efibrt ou the part of theoperator. Y

The ash-box A is furnished with a met-al lining, G, which renders itperfectly safe as a receptacle.

The coal-box B is made to fit inside of the flange or projection i uponthe upper edge of the ash-box A, thus making a close joint.

The arrangement of the sieves and their frames, in relation to eachother and the boxes A and B, shown and described, enables me to make thearticle very cheap, and yet durable and effective.

From thc foieg i11g description, it will be seen that I have produced asimple, safe, and yet very effective j coalsifter-onc b v which ashes ordust can be separated from the coal in a very quick and expeditionsmanner, and that, too, without exposing the operator to rising dust andashes during the operation.

It will be observed that the coal is subjected to a double sifting, oneupon the sieve E, and another while passing over the sieve H whichformsthe bottom of the frame or trough D.

A guide-piece, I, is fastened to the inner side of the frame or troughD, and extending up to the bottom of the frame C, whereby the coal isprevented from falling or being thrown into the ash-box while passingfrom the box or sieve C to the hod or other receptacle under the end Dof the trough D. The lower end of the trough D fits loosely in the boxB, so that its upper end can move with the sieve C when the lattermoves'.

Having described my improved coal-sifter,

What I claim therein as new, and of my invention, and desire to secureby Letters Patent, is'- 1. The combination, with the ash-box A andcoallbox B, of the sieves C E and D H, substantially as and for thepurposes set forth.

2. The combinationv and special arrangement ofthe sieves and frames Cand D, in respect to each other and the box B, substantially' as shownand described.

3. The combina-tion of the projection b and pin a with the box B andsieves C and D, as shown and described. A v
